How winning works

1 · The day in 30 seconds

1. Between 15:15 and 15:20 IST on a trading day, pick how each index will close — NIFTY 50, BANKNIFTY, SENSEX. Any subset: one call per index, and you can edit or cancel free until the 15:20 cutoff.
2. Every call is measured from the index's previous official close. Your chip says e.g. ▲ +50 → 25,050: you are calling that the official closing-auction value lands near 25,050.
3. After the auction (~15:45 IST) the day settles automatically against the exchange's published close. Winnings land in your NC wallet; there is nothing to claim.

2 · The three outcomes

• 🎯 Hit — graded by accuracy (up to 28×)

  Right direction, and the close lands inside your target's band. Exactly on target pays the full max — stake × 28. The further the close lands from your target, the less it pays, falling linearly to nothing at the band edge:

  payout = stake × 28 × (1 − miss-distance ÷ band)

  A ₹100-style example on a 100 NC stake: dead-on pays +2800 NC, halfway to the edge pays about half, landing right on the edge pays ~0. The multiplier rewards how close you were — never how far your target sat from the previous close. Every rung on the board carries the same 28× max.

• ➖ Flat — dead-zone refund

  The index barely moved — inside the dead zone around the previous close. Your stake comes back in full: no win, no loss, whatever direction you picked. This is the only mercy rule, there so a do-nothing day doesn't wipe everyone out.

• 💀 Miss — full loss

  Everything else — wrong direction, or right direction but outside the band. The stake is lost in full. There is no consolation tier.

3 · A worked example

NIFTY's previous close is 25,000. You stake 100 NC on ▲ +50 (target 25,050). The official close lands at 25,054 — 4 points off target, inside the ±15 band:

accuracy 1 − 4÷15 = 0.73 → pays +2,053 NC

Had the close landed dead on 25,050 it would have paid +2,800 NC. Had it closed at 25,100 — outside the band — it would have paid nothing.

4 · The board, per index

Each index offers strikes every few points, in both directions, spanning the whole ±3% closing auction band around the 15:15 anchor — you pick the exact level you expect the close to land at. Same max everywhere; the spacing, band and dead zone differ because the indices move on different scales.
